FIG. 1.

16S rRNA gene sequence analysis. The neighbor-joining phylogenetic tree of Burkholderia thailandensis strains was based on comparisons with 16S rRNA gene sequences of related bacteria. Pseudomonas aeruginosa DSM 50071 (GenBank accession no. X06684) was used as an outgroup for this analysis. Sequences were aligned and trimmed and gaps removed using the Wisconsin package, v. 10.3. Analysis was then done with MEGA 3.1 (Kimura 2-parameter, 1,000-step bootstrap) (http://www.megasoftware.net/). The bar indicates 2% sequence dissimilarity.
